The upcoming Blackberry Playbook still has some unanswered questions regarding its features, but one of those questions may have been answered as it will reportedly include its own proprietary video chatting software.

Research in Motion’s answer to the iPad phenomenon is gathering a lot of attention not only because it’s yet another high-profile tablet, but also because it has a heavy weight on its shoulder to bring RIM back from a deepening grave.

The Playbook will be coming to Sprint’s 4G network and it’s expected to be available on other carriers as well. There is no firm release date yet.
